<h1>Mesa 11.2.0 Release Notes / 4 April 2016</h1>

<p>
Mesa 11.2.0 is a new development release.
People who are concerned with stability and reliability should stick
with a previous release or wait for Mesa 11.2.1.
</p>
<p>
Mesa 11.2.0 implements the OpenGL 4.1 API, but the version reported by
glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) /
glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being used.
Some drivers don't support all the features required in OpenGL 4.1.  OpenGL
4.1 is <strong>only</strong> available if requested at context creation
because compatibility contexts are not supported.
</p>
